View east along the Denali fault trace through the north side of the Canwell Glacier. A crevasse is offset 3.52 +/-0.2m right-laterally and 2.05 +/- 0.2m up to the south. A stadia rod and 2-m-tall P. Haeussler for scale. This site has the largest vertical slip in ice of any site. Because debris has covered the crevasse crack to the right of the person in the foreground, the offset is measured on the inflection point where the snow surface rounds over into the crevasse. This number was checked against an estimate of the offset crevasse and found to be similar. Site PH312, km 102.9. Photo by P. Haeussler.
